Collateral networks in Moyamoya angiopathy (MMA) have a complex angioarchitecture. Delineation of deeply seated collateral networks (DSCNs) and image quality were prospectively evaluated in 10 patients using 7 Tesla TOF MRA and MPRAGE in comparison with conventional DSA. Seventy DSCNs were detected in DSA, 79 in TOF MRA, and 54 in MPRAGE. Detection of DSCNs was significantly better in TOF MRA than in DSA and MPRAGE. TOF MRA and DSA image quality were comparable, both were better than MPRAGE. Delineation of DSCN pathways in MMA using 7 Tesla TOF MRA was excellent and comparable to DSA.
